Description

The Kartboy rear endlinks are some of our customer’s more popular and favorable upgrades. For a cost effective means of suspension upgrades, you will be hard pressed to find anything equal in value. Reason being is that the factory end links are made of plastic, and can become soft after a while. The Kartboy units are a solid design, CNC cut and hard anodized 6061-T6 aluminum with stiff urethane bushings for the proper amount of dynamic flex.



Hand made in the USA, 100% guaranteed.

2012 wrx
Wrx 15 days ago
Installed these with white line 22mm rear sway bar. I didn't have access to jack sands or a lift at the time so I did the impossible and changed the sway bar without jacking or raising the car (way more difficult) it's been about 6 weeks now and I have it in the medium setting, there is less under steer when going hard in the corners and no fitment issues that others have had. Going slow turns around town it does sometimes make a popping sound but it's usually once a week or so and doesn't really bother me. Over all a must have for a bigger sway bar as stock will break and as good handling mods aswell

It's Kartboy... so basically a legend.

Bought these bad boys to go with my Perrin sway bar and it was a perfect match. I really feel like most Kartboy items speak for themselves with quality and they don't even compare to the stock ones. These are a must for any sway bar upgrade and Kartboy would be the first company that I would turn to.

Have these going on 5 years and they are holding up like a champ. These have been through 5 years of all season driving and are still perfect. Highly recommend!

These don't work with my sway bar. Wish I'd been warned.
cellobridges62330 12 months ago
They seem really solid and well made, but they don't work with the Whiteline 22mm adjustable rear sway bar. They cannot be used in any setting other than "hard." The "medium" setting is possible with some wiggling, but in this setting it will likely put a huge amount of stress on the hardware. I would not be surprised if something snapped. "Soft," is right out. Wish I had known this before making this purchase. I guess I'll have to buy some new endlinks.

Do not purchase with whiteline adjustable sway bar!

I was really surprised when I installed the well rated kart boy with my new whiteline adjustable sway bar. The end link only aligns with the stiffest hole on the bar and that is with the thinner spacer on the front side. With the 20mm on the stiffest setting and stock front bar I want off to autocross. Oops too stif the rear end kept trying to pass the front. So back to try forcing the kartboy link to a softer setting. I could force it to the middle setting but never the softest. A note to Tom kartboy confirmed I had installed all right and the end link would never be able to reach the softest setting hole, ugh! Even at the middle stiffness setting it looks bad the bottom of the endlink looks like the bushing is pulling out. I stuck the the link now and just received my Perrin spherical herring end link. So much better, it angles to all sway bar holes and makes the kartboy look very poorly designed..or at best a poor match to an adjustable whiteline bar.

  • Q: Fitment with whiteline adjustable 24mm rear sway bar for 08+ wrx  Hellraiserzzz 4 months ago

    Answer

    I already have these installed on my car along with whiteline's adjustable 24mm rear sway bar for my 08 wrx on the middle setting. Would i be able to get these on the soft setting? I've heared about people having fitment issues when going for the soft setting.


    • A: You shouldn't have any fitment issues on the soft setting.

  • Q: 2015 WRX Kartboy Rear endlinks with Eibach 7727.320 2015 F&R sway bar kit  cica191979782 7 months ago

    Answer

    I just wanted to confirm fitment of these endlinks with the Eibach sway bar kit. Will the Kartboy end links work in hard and soft setting on the rear Eibach sway bar without issue. Thanks


    • A: Yes, with how the Kartboy endlinks install you will want to move the washers in front of or behind in the control arm, but they can be used in other settings for the Eibach swaybar.

  • Q: 2008 WRX and Ralitek  Leo 1 year ago

    Answer

    Will this fit on a 2008 WRX with ralitek sway bars on stock height and on BC BR coilover when I switch. Do I need spacers for any fitment?


    • A: These should work without any problems, you may or may not need spacers as it varies per vehicle. Typically lowered vehicles need spacers

  • Q: Squeaking noise  Rallyracersti 1 year ago

    Answer

    I have these rear endlinks installed on my 15 wrx paired with a whiteline adj. sway bar. I have a lot of noise coming from the endlinks. All bolts are tight to rec specifications. What are my options to correct the noise?


    • A: These endlinks should not make any noise. We recommend loosening the bolts and re-torquing them with the suspension settled. You can remove the bushings and grease them, but that is generally not necessary. We also recommend checking the spacer placement to make sure the endlinks are as straight up and down as possible.


      Zach G. 1 year ago
    • A: So rue torque them while the car is completely on the ground? I would think the spacer placement would be correct as all bolts are tight. If the bolts were loose I could see that possibly being the noise, however all bolts are tight. With the car in the air on the lift and hand placed on the end link on either side moving it up and down there is a creaking noise. Again all bolts are tight.


      Rallyracersti 1 year ago
    • A: If the bolts are tightened with the wheels in the air, then extra stress will be added to the bushings while the wheels are on the ground because they will bind from the extra rotation while the suspension settles. We also recommend re-torquing the sway bar mounts with the suspension settled. If that does not get rid of the noise, then please contact customer service for further support.

  • Q: Hardware? Follow-up question  nyfowler 2 years ago

    Answer

    An earlier post states the following... You will reuse the factory hardware for the rear on the 08+ models, as it will fit through the control arm and the endlink. ...as it recommends re-using the factory hardware. I am unable to reuse anything because I am replacing a set of broken whiteline endlinks, and no longer have the stock parts. Do the kartboy rear endlinks come with two or four bolts? Thanks!


    • A: Two bolts are included as pictured, two factory bolts are reused from the vehicle. If you do not have the lower bolts in the control arm it is recommended to source those.
